Le domaine technique de la présente invention est celui de la solubilisation de composés bores, notamment et non limitativement en vue de l'adjuvantation de colles amylacées à l'aide de compositions borées.The technical field of the present invention is that of the solubilization of boron compounds, in particular and without limitation with a view to the adjuvanting of starchy adhesives using boron compositions.
Plus précisément, l'invention concerne l'incorporation d'acide borique et/ou de borates tels que le borax, dans des compositions aqueuses, par exemple les compositions amylacées du type de celles employées pour la fabrication de colles amylacées. Ces dernières sont utiles, notamment, dans l'industrie du papier/carton et plus particulièrement pour la manufacture de cartons et d'emballages en carton.More specifically, the invention relates to the incorporation of boric acid and / or borates such as borax, in aqueous compositions, for example starchy compositions of the type of those used for the manufacture of starchy adhesives.

ART ANTERIEURPRIOR ART
Les produits bores ou boraciques sont des dérivés de l'élément chimique bore (B) et on s'en référera à cette acception dans le présent exposé. Ainsi, au sens de la présente invention, ces dérivés sont notamment l'acide borique et les borates, comme par exemple le borax pentahydrate, le borax décahydraté, le pentaborate de sodium tétrahydrate, le métaborate de sodium octahydrate, le tétraborate de potassium tétrahydrate, le pentaborate de potassium octahydrate. Ces produits bores commerciaux sont largement utilisés comme ingrédients plus ou moins actifs dans des compositions de toutes natures, telles que des fertilisants, des détergents, des liquides de coupe métallurgiques, des médicaments, des produits cosmétiques, ou bien encore des produits à base d'amidon tel que les adhésifs pour papier/carton. Si l'on prend l'exemple des colles amylacées, il faut savoir qu'elles contiennent
de l'amidon natif et/ou de l'amidon modifié tel que les amidons réticulés. Pour qu'ils puissent développer leur pouvoir de véhicule, il est nécessaire de les chauffer en présence de soude, de manière à provoquer l'éclatement de tous les grains d'amidon. Cela forme un empois dans lequel l'amidon secondaire est ajouté. Ce dernier définit le pouvoir adhésif de la colle, car la conjugaison de la température, générée par les cylindres cannelés et l'application de la colle sur le carton, permet de former un complexe lié par le fait que l'amidon secondaire a éclaté. L'une des difficultés rencontrées par les applicateurs lors de la formation de la colle tient à la maîtrise de la viscosité. Cette dernière doit être fixée avec soin de façon à permettre une enduction aisée sur les supports à coller. Il est ainsi connu d'utiliser à cette fin des adjuvants bores, ayant des effets plastifiant, renforçant, filant et promoteur d'adhésion (entre autres) vis-à-vis de la colle amylacée.Boron or boracic products are derivatives of the chemical element boron (B) and we will refer to this meaning in this presentation. Thus, within the meaning of the present invention, these derivatives are in particular boric acid and borates, such as for example borax pentahydrate, borax decahydrate, sodium pentaborate tetrahydrate, sodium metaborate octahydrate, potassium tetraborate, potassium pentaborate octahydrate. These commercial boron products are widely used as more or less active ingredients in compositions of all kinds, such as fertilizers, detergents, metallurgical cutting fluids, drugs, cosmetic products, or even products based on starch such as adhesives for paper / cardboard. If we take the example of starch glues, you should know that they contain native starch and / or modified starch such as crosslinked starches. In order for them to develop their vehicle power, it is necessary to heat them in the presence of soda, so as to cause the bursting of all the starch grains. This forms a job in which the secondary starch is added. The latter defines the adhesive power of the glue, because the combination of temperature, generated by the grooved cylinders and the application of the glue on the cardboard, makes it possible to form a complex linked by the fact that the secondary starch has burst. One of the difficulties encountered by the applicators during the formation of the adhesive relates to the control of the viscosity. The latter must be carefully fixed so as to allow easy coating on the substrates to be bonded. It is thus known to use for this purpose boron adjuvants, having plasticizing, reinforcing, spinning and adhesion promoting effects (among others) vis-à-vis starch glue.
Classiquement le produit bore ajouté est constitué par du borax poudre, qui est incorporé en continu ou semi-continu dans la colle amylacée en formation. Cette forme borée pulvérulente est génératrice de plusieurs inconvénients. En premier lieu, la poudre de borax pose des problèmes de stockage puisqu'elle a une tendance à la reprise en eau, d'où des phénomènes de mottage. Or, il est clair qu'un produit motte se manipule difficilement, notamment parce qu'il ne s'écoule plus. En second lieu la poudre de borax (éventuellement mottée) est susceptible d'entraîner des imprécisions de dosage, en raison des incidents de blocage ou de bourrage pouvant se produire dans les moyens d'alimentation en poudre (trémie, vis sans fin) classiquement employés dans les procédés de fabrication de colle en continu. En troisième lieu, le borax poudre se mélange mal avec la colle amylacée en formation, ce qui nécessite des moyens d'agitation sophistiqués et nécessite de plus longues durées de réaction ou d'incorporation.Conventionally, the added boron product consists of borax powder, which is incorporated continuously or semi-continuously into the starch glue being formed. This powdery boreal form generates several drawbacks. First, borax powder poses storage problems since it has a tendency to take up water, hence caking phenomena. However, it is clear that a clod product is difficult to handle, in particular because it no longer flows. Secondly the borax powder (possibly mottled) is liable to cause metering inaccuracies, due to blocking or jamming incidents which may occur in the powder supply means (hopper, worm) conventionally used. in continuous glue manufacturing processes. Thirdly, the borax powder mixes poorly with the starch glue in formation, which requires sophisticated stirring means and requires longer reaction or incorporation times.
Pour tenter de surmonter ces difficultés, il a été proposé d'ajouter l'acide borique ou le borax hydraté sous forme de solution, tant il est clair que la manipulation d'un liquide et le mélange intime d'un liquide à un liquide sont plus simples que celle d'un solide. C'est ainsi que la demande de brevet européen Nβ 326 247 décrit un procédé d'addition d'acide borique ou de borate dans une colle amylacée en préparation. La
composition liquide borée mise en oeuvre dans l'invention selon cette demande antérieure, comprend 25 à 35 % en poids d'acide borique ou de borate, 55 à 35 % en poids d'eau et 20 à 30 % en poids de monoéthanolamine ou d'un composé organique polyhydroxylé. De telles compositions sont relativement pauvres en principe bore actif. Il s'ensuit que les concentrations théoriques, en anhydride borique ~O3 correspondantes sont encore plus faibles. Ce ne sont pas là des conditions optimales d'efficacité du produit bore en tant qu'adjuvant de colle amylacée. En outre, cela est révélateur d'une certaine incapacité de l'invention selon cette demande EP is- 326247, d'améliorer la solubilité dans l'eau de produits bores, laquelle solubilité étant connue pour être très faible. Par ailleurs, dans ce procédé de l'art antérieur, on prend soin d'effectuer la préparation de la composition liquide borée, à des températures de dissolution inférieures à 70 °C. Le but ainsi recherché est d'éviter la formation d'un complexe soluble entre le produit bore et les ingrédients du type monoéthanolamine ou composés polyhydroxyliques. Derrière cette disposition technique, on décèle la crainte d'une perturbation organique, voire d'un amoindrissement de l'efficacité du produit bore, dans le cas où il formerait un complexe. En définitive, cette composition liquide borée connue, est peu performante et par conséquent peu rentable sur le plan économique.In an attempt to overcome these difficulties, it has been proposed to add boric acid or hydrated borax in the form of a solution, since it is clear that the handling of a liquid and the intimate mixing of a liquid with a liquid are simpler than that of a solid. This is how European patent application N β 326 247 describes a process for adding boric acid or borate to a starch glue in preparation. The borated liquid composition used in the invention according to this previous application, comprises 25 to 35% by weight of boric acid or borate, 55 to 35% by weight of water and 20 to 30% by weight of monoethanolamine or d 'a polyhydroxy organic compound. Such compositions are relatively poor in active boron principle. It follows that the theoretical concentrations of boric anhydride ~ O 3 corresponding are even lower. These are not optimal conditions for the effectiveness of the boron product as a starch glue adjuvant. In addition, this is indicative of a certain incapacity of the invention according to this application EP is-326247, to improve the solubility in water of boron products, which solubility being known to be very low. Furthermore, in this process of the prior art, care is taken to carry out the preparation of the borated liquid composition, at dissolution temperatures below 70 ° C. The aim thus sought is to avoid the formation of a soluble complex between the boron product and the ingredients of the monoethanolamine or polyhydroxy compounds type. Behind this technical arrangement, there is the fear of an organic disturbance, or even a decrease in the effectiveness of the boron product, in the event that it forms a complex. Ultimately, this known borated liquid composition is ineffective and therefore not very profitable economically.
Le brevet américain US N* 4 332 609 décrit un fertilisant bore comprenant un composé d'acide borique avec une alcanolamine. Ce document n'a rien à voir, entre autres, avec l'utilisation de liquide bore dans l'adjuvantation de colle amylacée.US Patent No. 4,332,609 describes a boron fertilizer comprising a compound of boric acid with an alkanolamine. This document has nothing to do with, among other things, the use of boron liquid in the admixture of starch glue.
Force est donc de constater que l'art antérieur est imparfait voire défaillant, en ce qui concerne la fourniture d'un substitut bore liquide au borax poudre traditionnel, notamment dans le cadre de l'adjuvantation de compositions diverses, par exemple, des colles amylacées, des compositions décontaminantes pour produits radioactifs, des compositions biocides ou des compositions lustrantes et cirantes, entre autres.It is therefore clear that the prior art is imperfect or even faulty, with regard to the supply of a liquid boron substitute for traditional borax powder, in particular in the context of the adjuvanting of various compositions, for example, starch glues , decontaminating compositions for radioactive products, biocidal compositions or polishing and waxing compositions, among others.
Dans cet état de faits, l'un des objectifs essentiel de l'invention est de fournir un adjuvant bore, notamment, pour colle amylacée, adjuvant qui se présente sous forme liquide stable et qui soit doté d'une grande efficacité par unité de masse, au regard notamment des fonctions de promoteur d'adhérence, de plastifiant, et de renforçateur de cohésion, de l'adhésif amylacé.

EXPOSE DETAILLE DE L'INVENTION :DETAILED DESCRIPTION OF THE INVENTION:
II est du mérite de la Demanderesse d'avoir mis en évidence l'importance de la quantité théorique d'anhydride borique B2O3 dans la composition liquide borée
considérée. Il a pu ainsi être démontré qu'il est important de ne pas descendre en dessous d'une concentration théorique plancher en B2O3, afin d'obtenir un optimum sur le plan du compromis d'efficacité / solubilité dans l'eau pour le produit bore et d'autre part, que la présence d'un complexe solubilisé produit bore I composé aminé et /ou polyhydroxylé organique s'impose également. Le choix de la plage de pH est également important. Il détermine une bonne solubilisation des constituants de la composition liquide borée.It is to the Applicant's credit to have demonstrated the importance of the theoretical amount of boric anhydride B 2 O 3 in the borated liquid composition considered. It has thus been shown that it is important not to go below a theoretical floor concentration of B 2 O 3 , in order to obtain an optimum in terms of the compromise of efficiency / solubility in water for the boron product and on the other hand, that the presence of a solubilized complex produces the boron I amino and / or polyhydroxyl organic compound is also essential. The choice of the pH range is also important. It determines a good solubilization of the constituents of the borated liquid composition.
De manière surprenante et sans vouloir être lié par la théorie, la demanderesse a montré que la solubilisation du produit ou (soluté) bore passe, d'une part, par sa transformation (initialisation) en un complexe avec un composé aminohydroxylé et/ou avec un composé aminoalkylé et/ou avec un composé polyhydroxylé organique et, d'autre part, par sa transformation en un borate très soluble dans l'eau, e.g. le pentaborate par exemple de sodium.Surprisingly and without wishing to be bound by theory, the Applicant has shown that the solubilization of the product or (solute) boron passes, on the one hand, by its transformation (initialization) into a complex with an aminohydroxylated compound and / or with an aminoalkylated compound and / or with an organic polyhydroxylated compound and, on the other hand, by its transformation into a borate very soluble in water, eg pentaborate for example of sodium.
Connaissant l'équation de complexation et la solubilité de ce borate particulièrement soluble, en l'occurrence soluble à raison de 15,2 % poids pour le pentaborate de sodium, l'homme du métier peut déterminer des solutés de départ, les quantités stoechiométriques adaptées pour obtenir une complexation et, au besoin, une transformation optima en borate soluble.Knowing the complexing equation and the solubility of this particularly soluble borate, in this case soluble at a rate of 15.2% by weight for sodium pentaborate, a person skilled in the art can determine the starting solutes, the appropriate stoichiometric quantities. to obtain complexation and, if necessary, an optimum transformation into soluble borate.
Selon une variante, la solution aqueuse borée peut être exempte de produits aminés et/ou de composés polyhydroxylés et peut comporter un ou plusieurs additifs, du type biocide (fongicide / bactéricide) anti-mousse, tensioactif, etc.According to one variant, the borated aqueous solution can be free of amino products and / or of polyhydroxylated compounds and can comprise one or more additives, of the biocide (fungicide / bactericide) type, anti-foam, surfactant, etc.
La mise en oeuvre d'un adjuvant bore liquide formé par une solution aqueuse selon l'invention, peut parfaitement s'inscrire dans un mode continu ou semi continu de préparation, par exemple, de colle amylacée. Classiquement, une telle préparation précède immédiatement l'enduction de l'adhésif amylacé sur les supports à coller (papier, carton). L'incorporation de la solution selon l'invention s'opère aisément et une fois introduite, ladite solution se mélange intimement avec l'empois d'amidon additionné de soude. Cette étape est brève de sorte que la colle amylacée est rapidement dotée des propriétés que lui confère la solution borée : adhésivité, viscosité (texture filante) adaptée, renforcement de la cohésion.The use of a liquid boron adjuvant formed by an aqueous solution according to the invention can perfectly be part of a continuous or semi-continuous mode of preparation, for example, of starch glue. Conventionally, such a preparation immediately precedes the coating of the starchy adhesive on the supports to be bonded (paper, cardboard). The incorporation of the solution according to the invention takes place easily and once introduced, said solution mixes intimately with the starch mixture added with soda. This step is brief so that the starch glue is quickly endowed with the properties which the borated solution gives it: adhesiveness, viscosity (stringy texture) adapted, reinforcement of cohesion.
Il convient d'observer que la solution selon l'invention constitue un produit de
substitution à poids égal de borax poudre.It should be observed that the solution according to the invention constitutes a product of substitution with equal weight of borax powder.
Il est, également, important de souligner que la solution aqueuse borée selon l'invention est stable au stockage (plusieurs mois à des températures allant de - 5 °C à supérieures à 60 °C) et idéalement ne présente pas de produits non dissous, cristallisés.It is also important to emphasize that the borated aqueous solution according to the invention is stable on storage (several months at temperatures ranging from -5 ° C. to above 60 ° C.) and ideally does not have undissolved products, crystallized.
Outre la diminution du temps d'homogénéisation avec les composants de la colle amylacée en formation, la solution aqueuse borée selon l'invention augmente la température d'éclatement de la colle amylacée (température de gélatinisation). Il est clair que cela permet d'ouvrir la porte à l'utilisation d'amidon ayant à l'origine une faible température d'éclatement.In addition to reducing the homogenization time with the components of the starch glue being formed, the borated aqueous solution according to the invention increases the burst temperature of the starch glue (gelatinization temperature). It is clear that this opens the door to the use of starch originally having a low burst temperature.
L'incorporation de la solution selon l'invention est accompagnée d'une agitation.The incorporation of the solution according to the invention is accompanied by stirring.
Il va de soi que l'invention n'est pas limitée à l'application colle amylacée susvisée. Selon une disposition préférée de l'invention, le composé aminohydroxylé est choisi parmi les produits suivants : monoéthanolamine, diéthanolamine, triéthanolamine et leurs mélanges (entre autres), le composé aminé est choisi parmi les produits suivants : hydrazine, diéthylènetriamine, éthylènediamine et, entre autres, leurs mélanges et le composé polyhydroxylé organique est choisi parmi les produits suivants : glycérine, glucose, sorbitol, entre autres, et leurs mélanges.It goes without saying that the invention is not limited to the above-mentioned starch glue application. According to a preferred arrangement of the invention, the aminohydroxylated compound is chosen from the following products: monoethanolamine, diethanolamine, triethanolamine and their mixtures (among others), the amino compound is chosen from the following products: hydrazine, diethylenetriamine, ethylenediamine and, between others, their mixtures and the organic polyhydroxy compound is chosen from the following products: glycerin, glucose, sorbitol, among others, and their mixtures.
Le composé aminohydroxylé est susceptible d'avoir un effet d'abaissement du pH de la solution dont il faut tenir compte à propos de la régulation du pH.The aminohydroxylated compound may have a lowering effect on the pH of the solution which must be taken into account when regulating the pH.
Il pourrait être utile, dans certains cas, d'avoir recours à au moins une base forte minérale ou organique, pour ajuster le pH entre 7 et 8, dans la solution aqueuse borée considérée. Cette base est de préférence de nature hydroxylique, mais plus préférentiellement encore est choisie parmi les produits suivants : NaOH, KOH, LiOH, entre autres, et leurs mélanges. Cette base est au moins initialement (à la préparation) comprise dans la solution. Il est clair qu'ensuite, au moins une partie de cette base réagit avec les autres solutés de la solution.It could be useful, in certain cases, to use at least one strong mineral or organic base, to adjust the pH between 7 and 8, in the borated aqueous solution considered. This base is preferably of hydroxylic nature, but even more preferably is chosen from the following products: NaOH, KOH, LiOH, among others, and their mixtures. This base is at least initially (during preparation) included in the solution. It is clear that thereafter at least part of this base reacts with the other solutes of the solution.

De manière générale, la préparation de la solution mise en oeuvre notamment dans l'utilisation sus-visée, consiste à réaliser une solubilisation dans l'eau des solutés définis ci-dessus et ce, à une température de préférence comprise entre 20 °C et 55 °C. Le composé aminohydroxylé et/ou alkylaminé et/ou polyhydroxylé et le cas échéant la base forte, sont avantageusement tout d'abord mélangés dans l'eau, le ou les produits bores étant ensuite incorporés et malaxés.In general, the preparation of the solution used in particular in the above-mentioned use consists in carrying out a solubilization in water of the solutes defined above and this, at a temperature preferably between 20 ° C. and 55 ° C. The aminohydroxylated and / or alkylamino and / or polyhydroxylated compound and, where appropriate, the strong base, are advantageously firstly mixed in water, the boron product (s) then being incorporated and kneaded.
Plus précisément, on préchauffe (par exemple à 40° C) au moins une partie de l'eau constituant la solution et on incorpore sous agitation au moins une partie des composés aminés et/ou polyhydroxylés jusqu'à l'obtention d'un mélange homogène.More precisely, at least part of the water constituting the solution is preheated (for example to 40 ° C.) and at least part of the amino and / or polyhydroxylated compounds are incorporated with stirring until a mixture is obtained homogeneous.
On additionne ensuite dans le milieu sous agitation le ou les produits bores. Dans le cas où les produits bores sont formés par un mélange de borate et d'acide borique, le borate est avantageusement introduit le premier.The boron product (s) are then added to the medium with stirring. In the case where the boron products are formed by a mixture of borate and boric acid, the borate is advantageously introduced first.
On malaxe et une réaction exothermique de neutralisation intervient alors. On poursuit ensuite l'homogénéisation par malaxage du milieu pendant plusieurs minutes, par exemple, pendant une heure, en maintenant la température à des valeurs comprises entre 45 et 50 °C, e.g. pour une concentration en B2O3 d'environ 40 % poids. On obtient ainsi une solution limpide dans laquelle tous les solutés introduits sont solubilisés. Pour terminer, on laisse refroidir la solution de préférence en maintenant l'agitation, pour éviter la formation de peau d'orange.
L'incorporation des autres ingrédients tels que le biocide et/ou l'anti- ousse (entre autres), peut être effectuée à tout moment, mais il est préférable qu'elle intervienne après refroidissement, naturellement toujours sous agitation.It is kneaded and an exothermic neutralization reaction then takes place. Homogenization is then continued by mixing the medium for several minutes, for example, for one hour, maintaining the temperature at values between 45 and 50 ° C, eg for a B 2 O 3 concentration of approximately 40%. weight. A clear solution is thus obtained in which all of the solutes introduced are dissolved. Finally, the solution is allowed to cool, preferably while stirring, to avoid the formation of orange peel. The incorporation of the other ingredients such as the biocide and / or the anti-foam (among others) can be carried out at any time, but it is preferable that it takes place after cooling, naturally always with stirring.

Commentaires des résultats :Comments on the results:
Le fait de remplacer, dans des formulations Steinhall, le borax poudre par des produits boraxés sous forme liquide se traduit par une brusque augmentation de la viscosité dès l'addition du produit boraxé, ainsi que par une apparition du Vortex plus rapide.The replacement, in Steinhall formulations, of borax powder with borax products in liquid form results in a sudden increase in viscosity as soon as the borax product is added, as well as in a faster appearance of the Vortex.
